Much information about speech rhythm is believed to be embedded in low frequency
temporal modulations of the speech envelope. Using novel methods of spectral analysis we
construct a spectro-temporal modulation spectrum and extract low frequency temporal
modulations of spoken utterances to study the rhythmic structure of English and Hindi. The
results of our spectral analysis reveal a narrower temporal bandwidth for Hindi as compared
to English. We also calculate variability in syllable durations and find that variability in …
